According to the character of pathogenicity,antigen protein and host cell receptor,the review on Avian influenza viral (AIV) genome,host specificity and pathogenicity was made in order to understand it further at molecular level in the article.

Systematic studies of the biological characteristic including morphology,culture,physiological group,cell-wall type,nutrient utilization,nitrogenase activity and host specificity,were carried out on 12 strains isolated from the root nodules of actinorhizal plants of Myrica rubra,comparing with five Frankia strains symbiotically associated with Casuaria cunninghamiana,C.

The host-specificity of monogeneans in inland waters of China;
